ggspectra 0.3.6

, , , , 0

Package documentation web site at: https://docs.r4photobiology.info/ggspectra/

The changes from version 0.3.5, the current CRAN release, are:

New

  • Support for computation of colors using other chromaticity coordinates than the color matching function (CMF) for human vision.
  • stat_spikes(), useful for highlighting and labeling spikes in spectra.
  • Fitted peaks and valleys (experimental).
  • Annotations "wls" and "wls.labels" in autoplot() methods.
  • Update decoration() to support "wls" and "wls.labels".
  • Compatibility with ‘dplyr’ (>= 1.0.0).
  • Track changes in ‘photobiology’ 0.10.1 and 0.10.2.

Bugs fixed

  • Fix two bugs in ggplot() method for class object_spct.

NOTE: The updated package is on its way to CRAN.

photobiology 0.10.2

Package documentation web site at: https://docs.r4photobiology.info/photobiology/

This new update comes on the steps of the two previous ones (0.10.0, 0.10.1) and fixes a few bugs found since.

Changes from version 0.10.1 the most recent CRAN release, are:

Bugs fixed

  • color_of() was failing in some cases when it should not.
  • merge2object_spct(), merge_attributes(), interpolate_spct(), [ ] were in certain cases dropping attributes, in most but not all cases only filter.properties.
  • White LED example spectra may have had attributes inconsistently set.
  • Additional test cases were added (a suite of 4165 automatic test cases is used before release).

photobiology 0.10.1

, , , , , 0

Package documentation web site at: https://docs.r4photobiology.info/photobiology/

Continuing with the work released in version 0.10.0, this version includes significant new functionality as well as bug fixes and the rewriting of some smelly/ugly code previously used for the dispatch of math operators and functions. It also includes performance optimizations in the computations of color definitions from wavelengths.

In brief, this update brings: 1) improved handling of conversions among quantities used to describe filters, which required adding a mechanism to store properties of filters as metadata, and revising the code behind mathematical operations and mathematical functions related to filter_spct objects; 2) Support for use of arbitrary chromaticity definitions for tagging of spectra; 3) Changes to error checking and messages, including changing several earlier warnings into errors; several important bug fixes.

Changes from version 0.10.0 the most recent CRAN release, are:

New

  • setFilterProperties(), getFilterProperties(), filter_properties() and filter_properties<-().
  • print() method for filter properties.
  • convertTfrType(), convertThickness().
  • Example data for filters updated with filter properties.
  • Afr2T(), T2Afr(), any2T(), any2A(), and any2Afr().
  • is_absorptance_based().
  • wls_at_target() method for data frames.
  • rbindspct() now allows control of metadata copying

Bugs fixed

  • Serious bug in T2Afr() was causing wrong values to be returned!!
  • Serious bug in clean.object_spct().
  • Revise find_peaks() so that arguments passed to ignore.threshold and strict are obeyed also when span = NULL.

Defunct

  • T2T(), setAfrType(), getAfrType().

Note

Full functionality of convertThickness() and convertTfrType() requires filter_spct objects to have the new "filter.properties" attribute or contain a column "Rfr" with reflectance data like object_spct objects. This means that until packages ‘photobiologyFilters’ and ‘photobiologyPlants’ are updated, these functions cannot be used with the spectral data they contain.

NOTE: The updated package is on its way to CRAN.

photobiologyInOut 0.4.22

, , , , 1

The main changes from version 0.4.21-1 the previous CRAN release, are:

  • Revise read_fmi2mspct() adding flexibility to cope with variation in date and time formats used in headers of spectra.
  • Update for compatibility with ‘tibble’ (>= 3.0.0).
  • Update for compatibility with ‘photobiology’ (>= 0.10.0) which also provides compatibility with ‘dplyr’ (>= 1.0.0).
  • Depends now on ‘photobiology’ (>= 0.10.0).
